Package lme4 vignette, Using the familiar notation, the linear mixed effect model Pages 191-274. Because of the constraint that random effects be in the reduced in null models be the same as those from the full model, we use the meglm command rather than mixed, because meglm allows constraints() whereas mixed does not.
